Mechanical
Design: Leading Edge was the mechanical consultant
for this project which included running chilled water piping
from the central plant in Cuiccacali, underground to Zura residence
hall on the SDSU main campus. Zura acted as the hub with a new
pump room to Tenochca and Maya and Olmeca Halls. Upon recommendation
from Leading Edge, it was decided to run chilled water pipes
through the interior mechanical corridor of the Tenochca building
rather than on the exterior as determined by cost analysis.
New pump selection and design layout for central plant chiller
room was also completed.

Electrical
Design: Electrical details were included to show power
and conduit design for a new pump room in nearby Zura hall.

Other
Design Aspects: We also included fire protection design
and security. Landscape irrigation stub outs and site plan for
connection to existing irrigation was also shown.

Completed
mechanical design services including heating, ventilation, air
conditioning, and plumbing for 20,000 square feet of office
space, classrooms, and conference rooms. We also provided the
electrical design, including lighting design and power distribution
for entire building and site lighting. Designed the split system
air conditioning for classrooms and conference rooms with individual
thermostat in order to have better temperature control and a
higher comfort level. Duct liners were used in supply and return
plenum to minimize any sound from fan coil units. We placed
the heat pumps on the roof in a hidden area. Large package units
were used for high ceiling entrance areas. Our Title-24 Energy
Calculation confirms the compliance with building codes and
the California Energy Commission.

Project Overview:
The project will consist of architectural and engineering services
for the removal and replacement of the existing heating unit
in the mechanical room to include the boiler and associated
plumbing and equipment. Additional work to include a new intake
hood, louver system and control system for the air handling
unit serving the auditorium building at Carson Elementary School.
Install new boiler system. Install new SDCS district standard
automated energy management system.

Leading Edge
Consulting Engineers, Inc. provided electrical and plumbing
design to be installed in 23 portable/relocatable classroom
buildings. We designed water pipes, sewer pipes, sizes
and calculations. The project included gas, sewer, and
water riser diagrams.

We provided drawings of the site communications, fiber optics,
voice, data and fire alarm layouts for the school. We also provided
electrical design with lighting and power distribution for the
23 classrooms.

Mid City Adult School
We provided
drawings in AutoCAD of mechanical, electrical and plumbing design
retrofit. We made field investigations of existing mechanical,
electrical and plumbing systems and layouts, and made calculations.
We recommended retrofit design based on our field investigations
and equipment change out.

Farb Middle School
We replaced
a low-efficiency 300-ton chiller with two high efficiency screw
type chillers. Energy saving calculation was performed with
pay back analysis along with mechanical design for mechanical
room.

Hoover High School
Science Lab Building
Designed power
distribution and lighting for a new science building with 4
labs/classrooms.

Oceanside
School District

El Camino Real High School
Replaced existing
hot water heating system with new gas package units with thermostat
and economizer. We also designed outside air requirements per
UMC. The effected areas are now a gymnasium, a lounge, some offices,
and a team room. We were able to provide gas piping calculations,
sizing and layouts for all of the units, and provide condensate
drains and details. Demolition drawings were created to help remove
the existing heat exchanger that feeds off of the cooling tower.
We also replaced three old, larger, inefficient air handlers in
the Truax Theater building with three gas package rooftop HVAC
equipment.

San Luis Rey School
We provided
new gas package HVAC equipment with economizer and T-stat as well
as duct layout and sizing for lounge, computer room and offices.
Return air for all units and outside air requirement per UMC.
We provided gas-piping calculations, sizing and layouts for all
units, condensate drains and details.

Palm Quest
Mechanical design
of a new gas package HVAC equipment with an economizer and T-stat
for a lounge, computer room, and offices. We returned air for
all units and outside air requirements per UMC. We provided gas
piping calculations, sizing and layouts for all units, condensate
drains and details.

North Terrace
Installed a
new gas package HVAC equipment with an economizer and T-stat for
a lounge, computer room, and offices. We provided gas-piping calculations,
sizing and layouts for all units, condensate drains and details.
Demolition drawings were used to remove the existing heat exchanger
which feeds off of the cooling tower.
